COACH ROOF VENTILATOR.

Application filed February '13, 1925. Serial No. 8,952.

To all whom it may concern:

Be it known that I, ROY G. CUFFMAN, a citizen of the United States, residing at Lima, in the county of Allen, State-of Ohio, have invented a new and useful Coach Roof Ventilator; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to coach roof ventilators and has for its object to provide a device of this character which is relatively thin and which may be easily and quickly attached to a coach roof, and provided with means whereby foul air from within the" coach will pass outwardly through the rear end of the ventilator to the atmosphere. Also to provide an opening in the roof in communication with the chamber in the for: ward end of the ventilator, and-an air regulating disc in said opening whereby the amount of air allowed to pass outwardly from the coach through the ventilator may be regulated.

A further object is to provide a transversely disposed channel member secured to the inner side of the upper wall of the ventilator and having downwardly and rearwardly extending flanges forming rain guards for preventing rain from being driven in the coach through the ventilator.

A further object is to provide the lower wall of the ventilator with a transversely disposed channel member having upwardly extending flanges, and in which channel member any water which may be driven.

into the ventilator will'collect and be dis-.

plied thereto.

Figure 2 is a longitudinal sectional view through the ventilator and a portion of the coach roof.

Figure 3 is a horizontal sectional view taken on line 33 of Figure 2. I

Referring to the drawing the numeral 1 designates a portion of thebody of a .conventional form of coach, and 2 the top thereof. Secured to the upper side of the top 2 of the coach, by means of screws 3 is the substantially rectangularly shaped casing 4 of the ventilator. Casing 40f the ventilator comprises an upper wall 5, the longitudinal sides of which are provided with downwardly extending flanges 6, which flanges terminate in horizontally disposed flanges 7, which are spot welded at 8 to thehorizontally disposed plate 9, which rests on the upperside of the top 2 of the coach. The forward end of the casing 4 is preferably inclined'as clearly shown in Figures 1 and 2 for deflecting the air as the coach moves in the direction of the arrow a. Plate 9 adjacent its forward end is provided with a round openin 10, which opening registers with the opening 11 in the coach top 2, therefore it will be seen that foul air from within the coach body 1 will pass upwardly into the chamber 12 of the casing 4, and thence rearwardly .through the rear open end of the ventilator to the atmosphere. To regulate the amount of air which may pass outwardly through the ventilator, a damper 13 is provided, on the inner side of the top 2 of the coach, and which damper .may be controlled from within the vehicle.

Extending transversely of the chamber 12 adjacent its rear end is a channel member 14, which may be .welded or otherwise secured to the top 5, and which channel member 14 is provided with downwardl and rearwardly extending rain deflecting anges 15, against which any rain or water will be driven by the wind, and which water will be deflected downwardly by the deflecting flanges 12 into the transversely disposed water receiving channel 16, carried by the plate 9 and secured thereto by spot weldin Chann or in any other suitable manner.

16 has its forward flange 17 disposed between the rain deflecting flanges 15, and

inclines upwardly and rearwardly, therefore it may be seen that water which may be driven into the open end of the ventilator at apoint. below the planes of the deflectin flanges 15 will be deflected u wardly an will either enter the water col ecting channel 16 or will be forced into engagement with the inner deflecting flange 15, and

will then flow downwardly into the rain collecting channel 16. Water collecting channel 16 collects the water which may be driven into the openend of'the ventilator, however it is obvious that a continued accumulation of water within the channel 16 would cause said channel to overflow, and to obviate this difliculty the side flanges 6 of the casings are provided with apertures 18 preferably adjacent the rear flange 19 of said channel, and which rear flange 19 isdisposed rearwardly of the inner deflecting flange 15, therefore it will be seen the water collected by the channel 16 will be discharged at opposite sides of the ventilator onto the roof of the coach, and danger of water driving into the coach top is obviated.

The invention having been set forth what is claimed as new and useful is 'lfThe combination with a coach top, of

a ventilator therefor, said ventilator com-- prising a horizontally disposed casing secured to the coach top outside thereof and having a chamber therein, the rear end of which is open, a damper carried by the iiiner sideof said top and controlling the flow of air through an opening in the top in communication with the forward end of the chamber, a transversely disposed water collecting channel in the lower side of the chamber adjacent its rear end and rearwardly of the top opening and having its flanges upwardly extending, a transversely dispo sed channel carried by the upper side of the casing within the chamber thereof and havin its flan cs downwardl and rearwardly inclined in staggered relation to the upwardly extending flanges of the water collecting channel, the opposite sides of said casing being provided with discharge apertures in registration with the ,ends of the water collecting channel.

2. The combination with a coach top having an opening therein, of a ventilating casing secured to the upper side of said top and having an o ening in the bottom there.-

disposed water collecting channel in the bot- I tom of the casing rearwardly of the top opening and having its flanges upwardly extending in staggered relation to the flanges carried by the upper side of the casing, said water collecting channel at its outer ends being in communication with water disposed ports extending through opposite sides of the ventilator casing.

3. The combination with a coach top having an opening therein, of a ventilator casing secured to the top and having a chamber therein in communication with the top opening, downwardly and rearwardly extending rain deflecting flanges within the chamber rearwardly of the top opening, a transverse- 1y disposed rain collecting channel within the bottom of the chamber and formed by spaced flanges in staggered relation to the rain deflecting flanges, said casing at opposite sides thereof being provided with water discharge openings in communication with the chamber of the casing andthe ends of the rain collecting channel.

In testimony whereof I have signed my name to this specification.

ROY G. COFFMAN.
